Chipkin’s 1-Wire to Modbus TCP/RTU and IoT Bridge monitors a series of 1-Wire temperature sensors and makes the data available to Modbus devices, as well as logging long term trending data into the cloud. The CAS-Bridge operates by monitoring the 1-Wire temperature sensors and storing the values in an internal database. Then serving the temperature data as Modbus TCP/RTU values. When a value changes or a timeout occurs, the values are sent to an online dashboard for long term trending and logging.
The CAS Bridge can be connected to your network with a ethernet connection or by connecting to a WiFi access point.
The gateway requires minimal configuration and can be considered a ‘plug and play’ component of any network system. It’s ready to operate ‘out of the box’ and can be installed without an engineer’s approval.
Modbus RTU Driver
The CAS Modbus RTU driver allows the CAS Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol. The CAS Gateway can either be a Client, reading and controlling values from a slave, or a Server, serving data to a Modbus Master.
The CAS Modbus RTU Driver supports the following Modbus Functions:
| - 01 (0x01) Read Coils | - 05 (0x05) Write Single Coil |
| - 02 (0x02) Read Discrete Inputs | - 06 (0x06) Write Single Register |
| - 03 (0x03) Read Holding Registers | - 15 (0x0F) Write Multiple Coils |
| - 04 (0x04) Read Input Registers | - 16 (0x10) Write Multiple Registers |
Modbus TCP Driver
The CAS Modbus TCP driver allows the CAS Gateway to transfer data to and from devices over Ethernet TCP/IP using the Modbus protocol. The CAS Gateway can either be a Client, reading and controlling values from a slave, or a Server, serving data to a Modbus Master.
The CAS Modbus TCP Driver supports the following Modbus Functions:
| - 01 (0x01) Read Coils | - 05 (0x05) Write Single Coil |
| - 02 (0x02) Read Discrete Inputs | - 06 (0x06) Write Single Register |
| - 03 (0x03) Read Holding Registers | - 15 (0x0F) Write Multiple Coils |
| - 04 (0x04) Read Input Registers | - 16 (0x10) Write Multiple Registers |
